Ok, none of us have heard the damn thing, but if you look at what you can see from the design, it is clearly superior to the best of the rest, the Bose SoundDock. Apple also bother to post reasonable frequency response specs (+/- 3db 53-16k - yes, some genuine specs, note that our beloved friends Bose don't post any specs at all). It's also $50 more than the Bose wonder for something that if it's sound lives up to the way it looks like it could sound, will be huge order of magnitue better. I agree that it might be possible to put together a better sounding system for that money, but this is a one box, luggable, power supply flexible system with a little dock on the top which makes it incredibly convenient in many uses, particuarly as a bedroom system or whatever else one might want that for.
Am I the only one who thinks that it looks like an at least reasonably serious attempt at audio reproduction with an iPod flavour?
